those are chinese made blades. the quality and finish of european blades are way different. the cca blades are chinese made. i am not sure about the year but most european companies shifted to outsourcing blades in china due to the cost. that was probably as early 2010's. eventhough i can ask manufacturers where they make their blades, i would rather not trust it fully because if some would admit that theyir blades are made in china then maybe turned off. i see brands that openly say their blades are made in china like nittaku especially with their newer blades. some like adidas before which if compared to tibhar blades have better quality finish are made in china and that was confirmed to me by the blade designer. that blade designer saw the other brands in that same factory to which the adidas blades are made, the only difference is that the adidas blades have a separate production line but they are under the same factory. now, if you think the cca and drinkhall blades already for you have this high of a quality and they are already made in europe and not in china then you have not seen the quality of adidas blades. chian is capable of producing high quality finish much better than the cca or drinkhall series blades. again, my statements will not be confirmed by brands and most of the time they will even deny it. in my quest before to look for a factory, i asked around due to my gf's access to factories and I came across factories that produce euro blades and this aside from sunflex. the drinkhall series have a lower quality finish than the cca blades mind you. the cca series have a better quality but it is still not in the elite level and there are chinese made blades that have even higher quality than cca blades.
